Birth rate, mortality rate, immigration, and emigration rates are the key determinants of population increase. There are two primary models for growth:

Exponential expansion is a result of an infinite supply of resources and food. In this situation, the particular organism will grow exponentially.

Logistic expansion – As a result of the scarcity of resources during exponential expansion, individuals compete with one another. This first causes a lag phase. It is followed by acceleration and deceleration. A sigmoid curve shows the growth of a logistic process. Verhulst-Pearl Logistic Growth is another name for this.

Verhulst-Pearl Logistic Growth's equation is:

\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}\left(\frac{\mathrm{K}-\mathrm{N}}{\mathrm{K}}\right)

where N is the population density (at a certain period)

r = intrinsic natural rise rate

Carrying capacity is K.

Option 2  is the correct answer
